Universal AI Agents Architecture & Engineering Guides
Deep-dive technical architectural guides on autonomous reasoning loops, stateful runtime engines, Model Context Protocol (MCP), IETF agent RFCs, and agentic commerce.
TEST YOUR AI AGENT READINESS
Benchmark your domain against 20+ autonomous agent readiness criteria including DNS-AID, RFC 9727 API catalogs, WebMCP, and cryptographic origin proofs.
Core Concepts & Agentic Cognitive Patterns
Demystifying autonomous agents, state hierarchies, LLM routing, orchestrator-worker patterns, and persistent execution.
Runtime Engine & State Synchronization
State-synced base classes, callable RPC methods, durable fibers, sessions, compaction trees, and task scheduling.
Reasoning Harnesses & Tool Loops
The ReAct loop, 8 lifecycle hooks, idempotent server actions, client tools, and durable stream recovery.
Tool Execution & Code Mode Runtime
Isolated Linux sandboxes, Chrome DevTools Protocol browser automation, and Code Mode single-pass plan execution.
Model Context Protocol (MCP) & Governance
Streamable HTTP, SEP-1649 Server Cards, OAuth 2.1 token delegation, Agent Skills RFC, and security policies.
Agentic Payments, HTTP 402 & Commerce
HTTP 402 Payment Required challenges, Coinbase x402 on-chain micro-settlement, and Machine Payments Protocol (MPP).
Real-World Production Agent Archetypes
Architecting Chat, Slack/Messenger, Real-Time Voice, Browser CDP, and Asynchronous Email Agents.
API Catalog & RFC 9727 Linksets
Publishing machine-readable API catalogs using application/linkset+json for automated agent discovery.
Universal Agent Readiness Foundations
The core RFCs, bot rules, DNS-AID, and content signals required for full autonomous agent discoverability.
Markdown Negotiation for AI Agents
Serving high-density, token-efficient Markdown representations to LLMs via HTTP Accept header negotiation.
OAuth 2.0 Protected Resource Metadata (RFC 9728)
Enabling autonomous agents to discover authorization servers, token endpoints, and scopes via RFC 9728.
Auth.md: Machine Registration & Provisioning
Standardized instructions for autonomous agent onboarding, Dynamic Client Registration, and API key provisioning.
MCP Server Cards (SEP-1649)
Publishing Model Context Protocol metadata at /.well-known/mcp/server-card.json for instant agent discovery.
Agent Skills Discovery RFC v0.2.0
